The Synchro might actually be a bit under powered, but it fills in a missing niche while also being a solid beater
Some observations and ideas: - The AI seems unable to use Energy Spike effectively, which is a move from Electrode GB that allows you to search for a basic energy in your deck and put it on one of your Pokmon
There are also several aura cards that can stick to your opponents creatures
Once per turn, when another card or effect is activated (Quick Effect): You can negate the activation, and if you do, destroy that card, and if it was a monster, this card gains ATK equal to that monster's original ATK until the end of this turn
However, it evolves into Gyarados, a powerful Water/Flying-type Pokmon, starting at level 20, which makes catching a Shiny Magikarp particularly exciting for players.
